The SECCHI on the two STEREO spacecraft are identical suites of remote sensing instruments designed to observe coronal mass ejections (CMEs) at the Sun and in transit outwards to 1 AU. \n\nThe HI-1 telescope observes the inner heliosphere from 12 to 84 solar radii with the band-pass wavelength of 450-750 nm.",
